WINDOW.

SPECIFICATION forming part of Letters Patent No. 722,533, dated March10, 1903. Application filed December 4, 1902- Serial No. I331878. (Nmodel- To all whom it may concern:

Be it known that 1,,FRANK NENTWICH, a citizen of the United States ofAmerica, residing at East Liverpool, in the county of Columbiana andState of Ohio, have invented certain new and useful Improvements inWindows, of which the following is a specification, reference being hadtherein to the accompanying drawings.

This invention relates to certain new and useful improvements inwindows, and has for its object to construct a window in which both theupper and thelower sash may be swung inwardly, so as to facilitate thecleaning, and [5 also to provide novel means for locking the sash at anydesired height and to dispense with the sash cords and weights asordinarily employed in connection with windows, which are automaticallyheld at the desired positions.

In describing the invention in detail reference is bad to theaccompanying drawings, forming a part of this'specification, and whereinlike numerals of reference indicate like parts throughout theseveralviews,inwhich Figure 1 is a central vertical sectional View ofthe window constructed in accordance with my invention. Fig. 2 isoa rearperspective view showing the manner in which the. sash are swunginwardly to facilitate the cleaning. Fig. 3 is a front elevation of theupper sash, partly broken away to show the means for holding the same atany desired position.

Fig. 4 is an elevation, partly broken away,

3 5 of the lower sash, showing the means for holding the sash at anydesired position. Fig. 5.

is a horizontal sectional view of one of the rack-bars which are mountedin the windowframe, at one side thereof, and to which the windows arehinged. Fig. 6 is a horizontal sectional view through the frame with thesash removed.

In the accompanying drawings, illustrating my invention, 1 indicates thewindow-sill, 2 5 and 3 the respective sides of the frame, and 4 the topthereof. lhe frame also comprises front strips 5,'rear strips 6, andintermediate strips 7, the sash sliding between the strips 5 7 and 6 7.The sash are arranged so that they may be forced laterally toward oneside of the frame in order to disengage the same from between thesliding-rails at the oppo- "dow.

site side of the frame and permit of said sash being swung inwardly inorder to facilitate the cleaning of the windows when desired. Betweenthe strips 5 7 and strips 6 7, adjacent to the side 2 of the frame, arearranged rack-bars 8, which are provided with a rackface 9 and in theface, adjacent to the front of the window, are provided with a groove orseat 10, placed adjacent to one edge of the rack-bar and adapted toreceive the hinged rod 11. This hinged rod 11 passes through sleeves orkeepers 12, carried by the lower sash 14 and also by the upper sash 15.Springs 17 are attached to the rear face of the rackbars 18 and to theside 2, as seen in Fig. 1 of the drawings, and serve to hold therack-bars pressed normally outward toward the win- At the opposite sideof the frame, between the strips-'5 7 and strips 6 7, are arrangedstationary rack-bars 18. The sleeves 12 and the rods 11 form a hingeconnection between the sash-rail of one side of the sash and thevertical rack-bars 8. The frame is provided at its upper end-atthe-front portion thereof -with a recess 19, closed by the I bottom20,110 which is affixed the spring 21, having bowed ends which bearagainst the underneath face of the top 4. In order to swing out theupper window 15 toward the front of the window to facilitate thecleaning, I force the lower sash 14 upwardly, the mid-rail 22 engagingthe strip 20, compressing the spring 21 and allowing the upper end ofthe sash 14 to enter the recess 19. The upper sash 15 may then bepulleddownwardly until its top rail clears the lower mid-rails of thesash l4 and its lower rails clear the sill 1 of the frame, at which timethe said upper sash,

which has now been pulled down to the lower part of the frame, may beswung inwardly .inorder that the window may be readily cleansed. V

Means is provided for engagement with the locking-bars 8 and 18 to lockthe 'sasheither in the closed or partially-opened position. This meansfor the upper sash 15 I have shown as comprising two locking-rods 23,the ends of which project normally beyond the side walls of the sash andengage in the racks 9 of the rack-bars 8 and 18. These locking rodsoperate in ways 24, provided therefor in the lower mid-rail 25 of theupper sash 15,

this mid-rail having a recess 26 therein in which is pivoted a pair oflevers 27, which are connected by short links 28 to the locking-rods2,3. A plate 24 is secured to the sash and closes the ways 24 at thelower side. The bow-spring 29 is connected to the pivotpins 29, whichfasten the links 28 to the locking-rods 23, and thus normally hold therods 23 in the extended position, this spring being doubled as the twolevers 27 are drawn toward each other. For locking the lower sash Iprovide the lower mid-rail 30 with inclined ways 31, through whichextend the locking-rods 32, the other ends of the latter projectingnormally beyond the side rails of the sash and the inner ends of theserods being pivotally connected to links 33, that are in turn connectedto links 34, the latter being attached at their upper ends to thepivot-pin 35, carried by the thumb-piece 36, which operates verticallyin back of a plate 37, which is arranged in the recess 38 in the lowersash-rail 30. It will be observed that as the thumbpiece 36 is depressedthe lower ends of the links or levers 34 will be spread apart, while theupper ends of the links 33 will be moved toward each other, thusretracting the locking-rods 32 out of engagement with the rackbars 8 and18 and permit the vertical movement to be imparted to the sash 14. Thelocking-rods are held normally in engagement with the rack-bars by meansof the bow-spring 40, which is connected to the pivoted pins whichfasten the links 33 to the locking-rods 32. A suitable catch 39 iscarried by the lower sash-rail 30 in order to facilitate the raising ofthe window. It will be observed that when the thumb-piece 36 isdepressed and the locking-rods 32 turned so as to be disengaged from therack-bars, the lower sash will be free to be moved up and down in theframe, as desired; also, that when the levers 27 are drawn toward eachother the locking-rods 23 'will be retracted and the upper sash is freeto be moved up and down, the sleeves 12 of both sash sliding upon thevertical hinged rod 11. When it is desired toswingthe sash inwardly forthe purpose of cleaning, the lower sash 14 is moved laterally, so as todepress the spring 17, forcing the rack-bar 8 within the frame until theopposite end of the sash is free of the slide-rails 5 and 7. The sashmay then be swung inwardly on its hinge, so that ready access may be hadto either side of the glass. In order to swing the upper sash inwardly,the lower sash 14 is elevated until its upper end is within the recess19, and the upper sash is then pulled downwardly and moved laterally, soas to press its locking-bar 8 in order to clear the opposite side of theshaft from between the slide-rails 6 7, and this upper sash may then beswung inwardly in the same manner as was done with the lower sash.

Having fully described myinvention, what I claim as new, and desire tosecure by Letters Patent, is

1. In combination with a window-frame, spring-pressed rack-bars arrangedin the frame at one side thereof, a pair of sash hinged to saidrack-bars, and means for locking said sash at difierent positions in theframe, substantially as described.

2. In combination with a window-frame, spring-pressed rack-bars arrangedin the frame at the side thereof, stationary rackbars arranged in theframe at the opposite side thereof, a pair of sash hinged to thespring-pressed rack-bars, and means for looking the sash at differentpositions, substantially as described.

3. In combination with a window-frame, a

pair of spring-pressed rack-bars arranged in the frame at the sidethereof, a pair of sash hinged to said rack-bars, and having slidingmovement independent of the rack-bars, stationary rack-bars arranged inthe opposite side of the window-frame, and locking means for engagementwith said rack-bars to hold the sash at diiferent positions,substantially as described.

4. In combination with a window-frame, a pair of spring-pressedrack-bars arranged in one side of the frame, and having grooves in oneface, verticalrods mounted in said grooves, a pair of sash carryingsleeves or keepers to receive said rod whereby the sash are hinged tothe rack-bars to have a sliding movementindependentof the bars,and meansfor locking the sash at different positions, substantially as described.

5. In combination with a window-frame having a recess at its upper end,a pair of spring-pressed rack-bars arranged in one side of thewindow-frame, a pair of sash hinged to the rack-bars and having asliding movement independent of the bars, one of said sash adapted topartially enter the recess at the top of the frame when elevated, theother of said sash adapted to clear the first-named sash when loweredwhereby both sash may be swung inwardly, and means for locking the sashat dilferent positions, substantially as described.

In testimony whereof I aftix my signature in the presence of twowitnesses.
